Information entropy method of reliability synthesis for large complex systems
LI Zong-gen · Journal of Safety Science and Technology · 2008
The significance and applicable value of reliability multi-level synthesis for large complex system are described,the studying status and developing trend of system reliability synthesis are analyzed,then the problems and shortcomings of traditional reliability synthesis method based on probability and statistics theory were indicated,the reliability multi-level synthesis for complex system based on information theory was put forward,and the basic thought of entropy method of reliability assessment is given.By the use of general expression of the information entropy for discrete variable and addible characteristics of information,the reliability assessment method was studied for the system composing of different and same distribution type components according to equivalence principle of information quantity.The basic conversion models of the entropy method for component data and the reliability assessment formulae of complex systems were presented.
